In 1972 Shoe GOO was invented for "tennis toe" caused by dragging your shoe toe during service while playing tennis. It took two years of experiments with many gooey, gummy compounds before the perfect recipe was developed. This clear, rubbery adhesive was easily applied to shoes and hardens overnight restoring worn tennis shoes into "new" useable shoes again. The formula remains the same after all these years...not only do tennis players continue to use Shoe GOO, it has become very popular with skateboards and anyone not wanting to let go of those special shoes in the closet.
